Title: Improvements in the electric circuit arrangement of direct-current motors for hoisting machinery
IPC: B66C13/24
Filed: 1949-10-17
Abstract: 698,871. Control of D.C. motors. TELEMECANIQUE ELECTRIQUE. Oct. 17 1949 [Nov. 30, 1948], No. 26593/49. Class 38 (iii) In a control system for an electric motor driving reversible hoisting machinery a resistance in circuit with the shunt field winding 17 of the motor is controlled by a relay responsive to the motor armature current during the hoisting operation. For lowering, field resistance is controlled by a double-coiled relay having current and voltage coils. The full field of the motor is obtained during the early hoisting notches a vibrating relay RV1 coming into operation at the later notches so that contacts CV1 first regulate resistor 20 and then resistors 18-20 for constant power operation. During lowering the series field winding 10 is removed from circuit and, at the first notch, the armature is shunted by resistor 12. The armature shunting resistance is then increased and the armature series resistance reduced until the field resistance 20 is inserted. A relay comprising coils RV2 and RW2 which are additive or subtractive according as the motor drives the load or is driven by it then becomes operative to control resistor 19 through contact CV2 so that the motor reacts to the load, the field excitation being reduced and the speed increased at low loads.

Title: Hall effect magnetohydrodynamic generator
IPC: H02K44/08
Filed: 1963-07-04
Abstract: 1,048,474. Generators operating by electromagnetic interaction with fluids. COMPAGNIE GENERALE D'ELECTRICITE. July 4, 1963 [July 4, 1962], No. 26607/63. Heading H2A. A Hall effect MHD generator has the pressure of the working gas at the exhaust end of the duct lower than atmospheric pressure and the magnetic field at every point along the duct proportional to the working gas pressure. Fuel, oxidant and seed are burnt in a combustion chamber and the resulting gas expanded through a divergent conversion duct which has the opposed pairs of segmented thermionic electrodes connected together so that a Hall voltage is generated between the upstream or downstream pairs of electrodes. To provide the graded field the air gap between the polepieces of the electromagnet, which may use a superconducting winding, increases to provide a tapered duct. Preferably the product of flux density and electron mobility is between 2 and 30 and the reduced pressure attained by providing a suction device, e.g. liquid ring pump, ejector fan or the like at the exhaust end of the duct. The duet may be annular and have a central core member with the aerodynamically shaped electrodes completely crossing the duct or alternatively an annular electrode may be used. In a further modification the generator may be in the shape of a combustion chamber and tapered duct revolved around the Y-axis, Fig. 12 (not shown). In this case the magnet winding is centrally disposed and polepieces extend radially to co-operate with the duct. The use of low-pressure gas in the duct enables the Hall effect generator to have a normal generator connected upstream of it, Fig. 5 (not shown). The electrodes may be water-cooled and the exhausted gas, after seed removal, used in other energy extracting apparatus.

The heat flow from an irradiated test piece is measured by locating it inside a double-walled cylinder having a temperature-sensitive resistor on the outer wall of the inner cylinder. As shown (Fig. 1), an irradiated test piece in its casing 19 is suspended inside a first cylinder 14 surrounded by a second cylinder 1. A temperature-sensitive resistance wire 22 is wound round the inner cylinder 14. The space between the cylinders is filled with a gas under pressure. The outer cylinder 1 is maintained at a constant temperature as by a liquid bath. It is shown that the change in resistance of the wire 22, measured in a bridge circuit, is proportional to the total heat flow from the test piece. Means for calibrating the apparatus are described.

Abstract: 816,241. Draining pumps. IMPERIAL CHEMICAL INDUSTRIES Ltd. July 8, 1957 [Aug. 31, 1956], No. 26666/56. Class 102(1). A pump is arranged so that at the end of operation the inlet and outlet valves may be opened in order to drain the liquid from the pump. A bellows 7 is attached at 8 to the bottom of chamber 2. The upper end of the bellows is sealed and a rigid rod 11, protruding from the top of the bellows, is fixed to the top of the bellows and to the lower end of a spring 12 which abuts a shoulder 13 of a cavity 9 in communication with the interior of the bellows. A guide 14 for the rod 11 in the chamber 2 is provided with apertures for the passage of liquid being pumped. The liquid being pumped passes through inlet 21, chamber 2 and inlet valve 3, through passages 15, 16, 17, 18, 19 and 20 to a chamber 4 containing a second bellows construction as described above, and then past outlet valve 5 to the outlet 6. At the end of pumping fluid pressure, preferably oil, is fed through passages 10 to the interior of the bellows which moves the rods 11 to open the inlet and outlet valves 3, 5 and the liquid drains from the pump under gravity. In the position shown the bellows are preferably in a compressed state and the expansion of the bellows to open the valves is such that they remain under compression. A jacket 25 is provided, within which a heating fluid may be circulated, to apply heat to the liquid, such as trinitrotoluene, being pumped.

Filed: 1954-09-15
Abstract: 751,579. Projectile fuzes. AKTIEBOLAGET BOFORS Sept. 15, 1954, No. 26810/54. Class 9(1) An electric artillery fuze comprises electrostatic means for generating electric energy actuated by rotation of the projectile together with means for detonating . the fuze adapted to be actuated by the generated electric energy. The projectile 1 is provided with an electrically operated fuze adapted to function after a given delay or on impact, mounted in the screwed-in head portions 2, 3, which is separated from the explosive charges by a washer 4. The fuze comprises two condensers 7, 8 and a resistance 9, a discharge tube 10 being housed in an axial cavity in the condenser 7. An annular chamber 11 surrounding the condenser 7 is filled with a powder 15, which may be glass or colophony, and connected to the exterior of the shell by channels 12 having metal linings 13 'insulated from the portion 2. Plugs 14, which may be of lead, close the outer ends of the channels. The condenser 7 is connected to the tubular liners 13 and one of the head parts 2, 3, one or both of which are electrically conductive. The condenser 8 and resistance 9 are connected in series and are in parallel with condenser 7, while the discharge tube 10 and an electric igniter 16 are connected in series and are in parallel with the condenser 8. After firing the projectile, the plugs 14 escape due to the centrifugal force developed by rotation. The powder 15 as it is thrown out develops electrostatic charges due to friction with the tubes 13, thus charging the condenser 7, which in turn charges the condenser 8. When the condenser 8 is charged to the ignition voltage of the discharge tube, condenser 8 discharges through the tube 10 and the igniter 16, which in turn detonates relay charges 17 Should the projectile hit a target before the discharge voltage is reached, contacts 18 in the nose are closed and short-circuit the tube. 10, so that the condenser 8 discharges directly through the igniter 16.
